Đặt `C_{N_2(pư)} = x`

$N_2 + 3H_2 \rightleftharpoons 2NH_3$

`x -> 3x -> 2x`

Ta có: `K_C = ([NH_3]^2)/([N_2].[H_2]^3) = ( (2x)^2 )/( (0,5-x)(0,8-x)^3 ) = 3,125`

`=> x = 0,134

`[N_2] = 0,5 - 0,134 = 0,366M`

`[H_2] = 1 - 0,134.3 = 0,598M`

`[NH_3] = 0,134.2 = 0,268M`

`\%n_{N_2} = (0,366)/(0,366+0,598 + 0,268) .100\% = 29,71\%`

`\%n_{H_2} = (0,598)/(0,366+0,598 + 0,268) .100\% = 48,54\%`

`\%n_{NH_3} = 100\% - 29,71\% - 48,54\% = 21,75\%`
